I do want to state that this article appears to assume a stock tune controlling the engine it was tuned from the factory for (i.e. a Mustang GT EEC like an A9L or A9P controlling a stock Mustang GT 5.0L). As most of us DIY tuners know, this procedure doesn't work when the tune you are working with does NOT "fit" the engine you have due to modifications you've made (i.e. different injectors, cam, TB, MAF, heads, displacement, etc). Thus why idle tuning is such a popular topic for us DIY tuners on this forum.
